Since there are numerous 7400-series parts, the following groups related parts to make it easier to pick a useful part number. This section only includes combinational logic gates. For part numbers in this section, "x" is the 7400-series logic family, such as LS, ALS, HCT, AHCT, HC, AHC, LVC, ... Normal inputs / push–pull outputs
The 7400 quad 2-input NAND gate was the first product in the series, introduced by Texas Instruments in a military grade metal flat package (5400W) in October 1964. The pin assignment of this early series differed from the de facto standard set by the later series in DIP packages (in particular, ground was connected to pin 11 and the power ...
The 74181 is a 7400 series medium-scale integration (MSI) TTL integrated circuit, containing the equivalent of 75 logic gates [3] and most commonly packaged as a 24-pin DIP. The 4-bit wide ALU can perform all the traditional add / subtract / decrement operations with or without carry, as well as AND / NAND, OR / NOR, XOR, and shift. Many ...
The 74HC00 family followed, and improved upon, the 74C00 series (which provided an alternative CMOS logic family to the 4000 series but retained the part number scheme and pinouts of the standard 7400 series (especially the 74LS00 series)) . Some specifications include: [1] DC supply voltage; DC input voltage range; DC output voltage range
A single address decoder with n address input bits can serve up to 2 n devices. Several members of the 7400 series of integrated circuits can be used as address decoders. For example, when used as an address decoder, the 74154 [3] provides four address inputs and sixteen (i.e., 2 4) device selector outputs.
CD4048B = single expandable 8-input 8-function with three-state output, 8 choices for gate type: 8 NOR / 8 OR / 8 NAND / 8 AND / 4-4 AND-OR-Invert / 4-4 AND-OR / 4-4 OR-AND-Invert / 4-4 OR-AND [5] TTL 7400-series logic family: (in past decades, a number of AOI parts were available in the 7400 family, but currently most are obsolete (no longer ...
Because of the incompatibility of the CD4000 series of chips with the previous TTL family, a new standard emerged which combined the best of the TTL family with the advantages of the CD4000 family. It was known as the 74HC (which used anywhere from 3.3V to 5V power supplies (and used logic levels relative to the power supply)), and with devices ...
A simple controller can be built using the classic 7400 series of TTL logic integrated circuits. The counter used is the 74163, the multiplexer is the 74151 and the two decoders are the 7442 part. [1] The output from the counter selects what bit from the multiplexer input should be sent to the output Y, (the inverse of which is sent to the ...
